The UK government has announced sanctions against a further 370 Russian and Belarusian individuals and entities.
Since the Russian invasion of Ukraine began, the UK has sanctioned more than 1,000 of Russia and Belarus' most significant and high-value individuals, entities, and subsidiaries.
The Foreign Office said the additions to the government's sanctions list include Russian President Vladimir Putin's "key political allies, regime spokespeople and Kremlin-backed disinformation agencies".
Who's new on the sanctions list?
A total of 51 of those sanctioned on Tuesday are oligarchs and their family members, who have a combined estimated worth of more than £100bn.
It is understood the additions will bring the UK in line with restrictive measures already announced by the EU.
The Foreign Office said the UK will "continue to tighten the screw on the Russian economy in the coming days" as ministers make full use of powers "necessary to tackle the biggest security crisis in Europe since World War II".
Those added to the list on Tuesday include:
• Sergei Shoigu, a Russian politician and general of the army;
• Dmitry Medvedev, former PM and president of Russia and now deputy chairman of the Security Council of Russia;
• Mikhail Fridman, a founder of Alfa Bank, the largest non-state controlled bank in Russia;
• Petr Aven, the head of Alfa Bank until March 2022;
• Dmitry Peskov, Vladimir Putin's press secretary;
• Maya Bolotova, the daughter of Nikolai Tokarev, president of the Russian pipeline company Transneft;
• German Khan, one of the original founders of Alfa Group Consortium;
• Maria Zakharova, Russian Foreign Affairs spokeswoman;
• Alexey Mordaschov, a member of Russia's richest family;
• Alexander Ponomarenko, chairman of the board of Sheremetyevo, the biggest airport in Russia;
• Andrey Melnichenko, the founder of EuroChem Group, one of the world's leading mineral fertilizer producers;
• Viktor Vekselberg, owner of the Renova Group, a Russian conglomerate with interests in aluminium, oil, energy, and telecoms;
• Dmitry Pumpyansky, owner and chairman of OAO TMK, a leading global manufacturer and supplier of steel pipes for the oil and gas industry;
• Vadim Moshkovich, chairman of the board of directors of Rusagro Group, the second leading Russian producer of beet sugar;
• Mikhail Mishustin, a Russian politician and the current prime minister of Russia;
• The Internet Research Agency, a notorious internet "troll farm".
Truss: 'We will keep on increasing the pressure'
Those individuals sanctioned today will have their assets in the UK frozen, which means no UK citizen or company can do business with them, and they are also banned from travelling to or from the UK.
Foreign Secretary Liz Truss said the UK is going "further and faster than ever in hitting those closest to Putin".
She added: "Working closely with our allies, we will keep increasing the pressure on Putin and cut off funding for the Russian war machine,"
